FIG. 3 schematically shows the configuration of the connection coupler according to the embodiment of FIG.

In these figures, reference numeral 10 denotes goggles worn on the wearer's face so as to cover the eye portion. The goggles 10 include a substantially transparent front surface portion 11 located in front of the eye when worn, a main body portion 12 having a flexible one end portion surrounding the peripheral end of the front surface portion 11, and the other end of the main body portion 12. It is provided with a mounting belt 13 for closely fixing the portion to the face of the wearer, and a hydrogen gas supply port 14 provided in the main body portion 12. Hydrogen gas is configured to be supplied to the internal space formed between the front surface portion 11, the main body portion 12, and the face of the wearer through the supply port 14.

Although the front surface portion 11 is made of a transparent glass plate member, the front surface portion 11 may be made of a transparent plastic plate member instead of the glass plate member.

The main body 12 is made of a flexible rubber member or plastic member, and a plurality of vents 12a for ventilating the internal space to the outside air are provided on the upper end surface and the other end surface thereof.

The wearing belt 13 is a stretchable and flexible belt, and is configured to be hung on the wearer's head so that the main body 12 is closely fixed to the wearer's face. The wearing belt 13 is provided with a belt adjusting portion 13a, and the belt length can be adjusted so that the goggles 10 are appropriately brought into close contact with and fixed to the wearer's face.

The supply port 14 is provided at an arbitrary position of the main body portion 12, and is configured so that the main body portion 12 can be inserted to communicate the internal space with the outside. In the present embodiment, the supply port 14 is a tubular body that passes through the wall surface of the main body portion 12, and a plug of a one-touch coupler communicates with one end thereof.

As shown in FIG. 2, the eye strain recovery device is made of a socket 15 configured to be connectable to the plug of the supply port 14 of the goggles 10 with one touch, and a plastic having one end connected to the socket 15 (for example,). A tube 16 (made of acrylic resin) and a hydrogen gas supply source 17 connected to the other end of the tube 16 are further provided. The hydrogen gas supply means of the present invention is configured by the socket 15, the tube 16, and the hydrogen gas supply source 17.

In the present embodiment, the hydrogen gas supply source 17 is connected to the hydrogen storage alloy canister 17a, the switch mechanism 17b which is connected to the hydrogen storage alloy canister 17a and can turn on / off the supply of hydrogen, and the switch mechanism 17b. It is provided with a flow control valve 17c composed of, for example, an orifice or the like that adjusts the flow rate of hydrogen gas. The hydrogen storage alloy canister 17a is a cylinder-shaped container containing a hydrogen storage alloy that can reversibly absorb and release hydrogen at room temperature and low pressure by an exothermic reaction and an endothermic reaction, and is generally commercially available (for example,). YMC Co., Ltd.). The hydrogen storage alloy canister 17a does not correspond to the high pressure gas referred to in the High Pressure Gas Safety Act because the internal pressure can be set to 0 to 0.99 MPa and does not exceed 1 MPa. Therefore, it can be easily used in offices and hospitals. Further, the size of the container can be designed as small as several cm in diameter and about 10 cm in height. Further, since the hydrogen storage alloy can be used by reabsorption even after hydrogen is consumed, there is an advantage that the cost is reduced by repeated use. As described above, according to the hydrogen storage alloy canister 17a, it is possible to safely supply high-purity hydrogen gas while being lightweight and compact, and it can be used repeatedly. A pressure adjusting valve may be provided instead of the flow rate adjusting valve, or both a flow rate adjusting valve and a pressure adjusting valve may be provided. Further, instead of the hydrogen storage alloy canister, an electrolysis type hydrogen gas generator or a chemical reaction type hydrogen gas generator may be used.

As shown in FIG. 3, the one-touch coupler is connected by inserting a plug communicating with one end of the supply port 14 into the socket 15, and is disconnected by pressing the push button of the socket 15. In the present embodiment, the one-touch coupler has a structure in which both the plug and the socket 15 have valves inside. Therefore, when the plug is connected to the socket 15, the fluid can flow in both directions, but when the plug and the socket 15 are disconnected, both the plug and the socket 15 are closed and the flow of the fluid is blocked. It is configured in. In the present embodiment, as the one-touch coupler, a commercially available general plastic fluid coupling, for example, a cube coupler (registered trademark) of Nitto Kohki Co., Ltd. is used.

Hereinafter, a method of actually using such an eye strain recovery device will be described.

With the plug connected to one end of the supply port 14 and the socket 15 connected, first, the mounting belt 13 is hung so that the main body 12 of the goggles 10 is closely fixed to the wearer's face.

In this state, when the switch mechanism 17b of the hydrogen gas supply source 17 is turned on, the hydrogen gas from the hydrogen storage alloy canister 17a is discharged from the goggles 10 via the switch mechanism 17b, the flow rate adjusting valve 17c, the tube 16 and the supply port 14. It flows into the internal space. The inflow amount is about 20 mL / min.

The hydrogen gas that has flowed into the internal space of the goggles 10 comes into contact with the wearer's eyes, which makes it possible to recover from eye strain. The hydrogen gas that has flowed into the internal space is mixed with the air in the internal space by convection due to the wearer's body temperature, and a part of the hydrogen gas is discharged to the outside through the plurality of vents 12a, and finally. The hydrogen gas concentration in this internal space is 4% or less. The hydrogen gas supply source 17 is configured to mix hydrogen gas and air to obtain a mixed gas having a hydrogen gas concentration of 4% or less by using an air pump or the like (not shown), and supply this mixed gas to the goggles 10. You may.

In this way, when recovering from eye strain with hydrogen gas or a mixed gas thereof, the front surface portion 11 in front of the eye in the goggles 10 is made of a transparent glass plate member or a transparent plastic plate member, so that the eye. Can be continued without interruption of work using. Therefore, it is possible to recover from eye strain while performing all kinds of work using the eyes.

If the switch mechanism 17b of the hydrogen gas supply source 17 is turned off, the supply of hydrogen gas to the goggles 10 can be stopped. Even if the connection between the plug of the one-touch coupler and the socket 15 is disconnected, the supply of hydrogen gas to the goggles 10 can be stopped. In this case, since the valves (closing mechanism) inside the plug and the socket 15 are closed, hydrogen gas does not leak to the outside.

As described above, according to the present embodiment, since hydrogen gas is supplied to the internal space when the goggles 10 are worn on the face, it is possible to recover from eye strain such as eye fatigue and pain. Moreover, since the front surface portion 11 located in front of the eye is transparent when worn, it is possible to recover from eye strain while performing work using the eye.

The embodiments and examples described above are all exemplary and not limited to the present invention, and the present invention can be carried out in various other modifications and modifications. Therefore, the scope of the present invention is defined only by the claims and their equivalents.
